FIRE ALARM STICKER Filed March 14, 1960 W4) fi c h zg INVENTOR United States Patent Ofiiiee Patented Jan, 16, 1952 3,016,872 FIRE ALARM STICKER Vira Hughey, Stigler, Qkia. Filed Mar. 14, 196i), Ser. No. 14,998 3 Claims. (Q. 1161ll6) This invention relates generally to a fire alarm warning device, and in particular to a paper disc containing an explosive that may be stuck to the wall by an adhesive alfixed to the back of the paper disc.

This invention is a fire alarm of the general size of a. button and is made of paper, plastic or other suitable material. The fire alarm sticker is generally constructed by placing an explosive between two pieces of paper and sealed with same. The seal confines the explosive and excludes moisture which might otherwise harm the reliability of the sticker. Any suitable explosive such as A of 1 cc. of silver fulrninate, is satisfactory so long as it will explode upon the application of heat.

It is, therefore, an object of this invention to provide a small inexpensive device for sounding an alarm when fire breaks out in the home, barn, brooder houses, etc.

It is a further object of this invention to provide a fire alarm sticker that can be applied to a wall without having to nail or screw the alarm thereto.

It is a still further object of this invention to provide a fire alarm that can be stuck to the Wall and remain permanently attached thereto.

Further objects and advantages of this invention will become apparent to those skilled in the art from the following description and claims when read in view of the accompanying drawing, in which:

FIGURE 1 is a top view of the fire alarm sticker;

FIGURE 2 is the back view of the sticker;

FIGURE 3 is a cross section of the fire alarm sticker taken along the line 3-3 of FIG. 1;

FIGURE 4 is a top view of the sticker with top removed showing explosive 5.

Referring to the figures generally, a fire alarm sticker generally comprises a bottom disc 11, a top disc 10, attached to the disc 11 at their respective outer peripheries. An adhesive 12, which may be of any well known type, is applied to one side of disc 11. An explosive charge 5, is placed between disc 11 and disc 10.

In operation the fire alarm sticker is placed with the adhesive surface 12 against the wall or other surface as, for example a ceiling. If a fire should start, the hot air from the flames would heat the sticker and cause the explosive to detonate and sound the alarm that a fire had started.

The discs are not necessarily restricted to that particular form. They could, for example, be square, ovate, or other decorative shape. They may also be of any color to suit the user.

Thus a novel fire alarm sticker has been described that permits ease of installation. A plurality of stickersmay also be used to warn of fire in any location in a home or other buildings. Stickers in more than one location will also warn as the fire spreads.

Although this invention has been described with respect to a particular embodiment thereof, it is not to be so limited, as changes and modifications may be made therein which are within the spirit and scope of the invention as defined by the appended claims.

I claim:

1. A fire alarm sticker comprising, a first non-metallic sheet, a second non-metallic sheet, an explosive charge, said explosive charge secured between said first and second non-metallic sheets, said first and second sheets being sealed together at their peripheries, and an adhesive placed on the outside surface of one of said first or second sheets, whereby said fire alarm sticker will be rigidly secured to a desired location when the adhesive portion of said sticker is pressed thereto.

2. A device as described in claim 1 wherein said sheets are made of paper.

3. A device as described in claim 1 wherein said sheets are made of plastic.
